content creation through rest api

[soumyajit]

I want to create new content in particular spaces using rest api. 

Background: We have another application, from this application if any user creates new content then it will be created automatically into the confluence also, through rest api.

Hi @soumyajit, can you be more specific about your question?

Assuming if you want to create content through api rest  read tihis:

But I advise you to start with simple things like get or put methods, postman is very useful

I want to create a new page into a particular space using the rest api. Also multiple user can create page through rest api. First we need to check using authentication & when authentication passed then they can post data through rest api.  So my question:

1. How to check user authentication using rest

2. Once it is passed then they can create content through rest
